SUPPORTING DEVICE FOR AUTOMOBILES.

To all whom t may concern:

-Be it known that we,wEDw1N H. SADLER and ERNEST L.' HALL, citizens of the United States, residing atfHuntington Park, in the county of Los Angeles and State of California, have invented new and usefnllmprovements in Supporting Devices for Automobiles, ofwhich the 1 following is`a specification.

This ,invention relates tonew and useful improvements in supporting devices for automobilesk and the principal object of the invention isto provide means kfor lifting the wheels of theautomobile from the ioor of the garage. f f r f i" Another object of the'invention is to provide meanswhereby the momentumrv'of the automobile fwill'foperatel means to raise the Wheels off the ground. n

- Another object of the invention is to provide forv lowering the rear wheels, to Aprovide traction, for'releasing theparts Jfrom the4 lifting means. f

vThe invention alsov consists in certain other features of construction and in the combination `andfarrangement of the several parts, tofbe hereinafter fully described, illustrated in ,the` accompanyin drawings and specifically pointed" ont 1n the ap'- pended claims. f 'i n In describing our invention in detail, reference will lbe had tothe accompanying drawings wherein likecharacters denote like or corresponding parts throughout the several views, and in whichtv s Figure 1- isa lan view of the invention. Fig. 2 is a si ey elevation. Fig- 3 is a side view showing the lifting means Vfor they rear blocks in inoperation position. l

- Fig. 4 is a longitudinal section. Fig. 5 is a cross section on `line 5`5 of Fig. l y

Fig. 6 is a section on line'6-6'of Fig. 3.

In these views 1 indicates a pair of supporting-"beams, on which kis located a pair of front inclined blocks 2 and a pair of rear inclined blocks 3. f' The inclination ofthe front edges of these blocksis .greater than thatr of the'rear edges. The rear blocks are provided with substantiallyrat portions at their apexes. f On each of the front blocks is slidingly mounted an axle engaging member 4, which engages the inclined edge ofthe block. Anangleiiron 5 is secured-to i Specification of Letters Patent. Patented Rial. 18, 1919. l Application led September 21, 1918. Serial No. 255,155.

the upper edge of this member. A spring 6 normally holds the member at the rear or lower part of the inclined edge of the block. If desired, the member may be connected with the block by the tongue and' at A. The endsvof the U are so spaced as t0 receive the axle with the part thereof resting oneach end. The members 8 are connected by links V9 to a sliding frame 10. This frame is connected with the blocks 3 by the tongue and groove connections 1l. As shown, the links 9 have their yends pivoted kto the members 8 and the frame and springs -12 connect' said links, intermediate their ends, with said frame.

:13 indicates a bar having one end connected with the sliding frame `10 'and its other end extending between the front blocks 2. A guidebar 14 is connected with the bar 13 and this guide bar is suitably supported. The front end of the bar 13 is provided with slots 15 and a bracket 16 is slidingly connected with the bar 13 by means of the bolts 17 passing through said slots. The bracket is normally held in' its rearmost position 'by means of the spring 18. The-'bracket is provided with an upwardlextension 19, which is provided with a vertical bore 2O` The `bore receives the end of a rod 21 which is normally held in the upper end of said bore by spring 22. This rod is provided with a bent upper end as shown. f

The" rod 21 extends high enough to be struck by the front axle, indicated at C, of the automobile. The further movement of the automobile will cause the bracket to move forwardly and this action will cause the., bar V13 to pull the slidin frame forwardly so as to force the mem ers 8 up thel inclined edges of the blocks 3. The parts are so positioned that as the automobile moves forward and the members 8 move up the incline the truss rods will enter the space between the legs ,of the members 8 and said'members will engage the rear axles near the end of their movement so as to force .the rear wheels oil' the floor when the members reach the end of their movement and are resting on the flat portions. it about the time the front axle strikes the rod 2l it will also come in contact with the front members d so that the momentum of the automobile will cause said members to slide up the inclined blocks and thus lift the i'ront wheels ed the iioor.

ilhe rear members are vertically movable by means oL a pair of lever nil which are pire oted to the lower part of each of the members 3 by the pins These pins 25 pass entirely through the member and short levers 2G are secured to the pins at the other side oi' the members. The upper parts oi' the levers 24 are slotted as at 2l and these slots arc engaged by pins QS carried by lii is 29 which have their ends pivoted as at- 30 to a plate 3l secured to the central part of -the member rihis plate is provided with a slot 32 and braces pivoted to the links 29 have their ends pivoted together by a pin 3e which engages said slots. Springs B5 conneet the upper parts oi the levers 2l with the member 3 and said springs tend to hold the levers in raised position so as to hold the members in their uppermost positions. r-l`he links are o1 such a length that the levers are held at a slight incline to the eottom or the blocks il, so that the weig ot the automobile tends to tilt the levers and permit the blocks to move to their lowest position. The parts are held in this position by means of spring catches carried by the members 3 and engaging the levers. rlliese catches are operated :trom any desired point by means or" the cables 37.

lt will t ius be seen that when it is desired to remove the automobile from the device it is simply necessary to withdraw the catches by pulling the cables 87. This action will allow the weight of the car to lower the members 3, 'by causing the levers to rock on the-ir pivots, so that the rear wheels will come in contact with the door. Then, by starting the motor, the automobile may be backed oli the device. ln this action the parts will be returned to normal position by the movement of the automobile and the springs. lf it is desired to run forward, instead of backward. the forward movement of the automobile will push the sliding member over the highest parte of the blocks and down the stront inclined edges ot the blocks so that the axle will be released the same as if the automobile was backed. As the front axle moves downwardly it will engage the bent end of rod 2l and force said rod downwardly outI of its way.

The rear blocks 3 are guided in their vertical movement by the pins 38 engaging the recesses 39 formed in said blocks.4

Bumpers l0 are located adjacent the iront blocks against which the iront wheels of the automobile will strike to prevent the car.

ine'aeic 'trom passing over the device. These bumpers must be removed ii the automobile is to be moved forwardly oil the device.

if it is desired to raise the wheels on yone side only of the machine, this can be done by 'removing the. sliding members on the opposite side oi the device. y

it will be seen that the rear blocks vare ci less height than the liront blocks so that the iront axle can pass over the rear blocks. 0f course, it will be understood, that the automobile ina'y be backed upon the device but to do this the blocks must be reversed.

iter an automobile leaves the device the parte are in a position to receive another automobile.

lt is thought from the foregoing descrip tion that the advantages and novel features of cnr invention will be readily apparent.

ille desire it to be understood that we may make changes in the construction and in tlhe combination and arrangement of the several parts.l provided that such changes tall within the scope ot the appended claims.

`We claim as our invention:
